Merck 109191 MAS-100 NT

The industry standard for viable air sampling

The MAS-100NT® portable microbial air samplers are the industry standard for use in critical environments. These compact yet sophisticated devices are the preferred choice for those demanding the highest quality in microbial air monitoring.

The MAS-100NT® systems feature a new 300-hole perforated lid for increased collection efficiency and impaction speed. Both systems utilize standard 90 – 100 mm agar plates or can be adapted to fit 55 – 60 mm contact plates allowing for a low consumable cost and greater flexibility.

Sampling at 100 litres per minute, these systems have the highest airflow accuracy available at ± 2.5 %, compared to others that can be as high as ±10 %. The integrated flow sensor allows the user to freely interchange the perforated lids without affecting the accuracy or the calibration of the unit. Sampling volumes are also easily configurable between 1 and 2,000 litres.

The units have an impact velocity of 19.6 meters per second equivalent to Anderson 6 and isokinetic flow rate that will not produce turbulence in a laminar flow environment. The new SQS function will allow for smaller sampling volumes over longer periods of time, up to 50 sequences over 24 hours.

The new MAS-100NT® systems are controlled using a new menu driven, larger illuminated display allowing for quicker navigation. A programmable start delay of up to 60 minutes allows for personnel to be out of the sampling area when the sampling starts and a new audible alarm indicating the interruption of a sampling.
